been using my mba for a few weeks now and i noticed that even when fully charged and still pulled into the charged the battery percentage still says 99% i have yet to see it reach and stay at 100% while being plugged in. is this normal? i am on my 5th cycle if that matters.
"Does it harm the battery or reduce battery life, to use the AC adaptor for extended periods while the battery is fully charged?"Someone answered, "I would have to disagree with the others who say that it hurts your battery & reduces battery life by keeping your AC adapter plugged in with a full battery.I have done extensive research and asked many apple employees and have always come to the same conclusion. They all say to keep your laptop plugged into an power supply whenever possible. Only use your battery if you have to, in those times when you are not near a power supply.
So I charged my battery to 100% and then unplugged it from the charger. Thats when the battery dipped to 97% instantaneously. It was very odd and somewhat scary. I just bought this MBP 2 days ago! Anything i might be missing? Is it supposed to do that?
I have a MacBook Pro. Keeps completely shutting down all the time when its fully charged and at random times when it is at 65% for example. Do I need to get a battery replacement? Or do I have a virus?
I have a new 13" MBP (1 week old), and the battery is supposed to be fully charged, according to the battery menu and some hardware monitor app. Well, the same menu says the battery is 95% charged, while the MBP is hooked to the home's sector. What the heck is that ? Last week, the information was consistent (100% recharged).
What is happening here ? Is the battery defective or is this normal ? I'm new to the laptop world, so I need to understand what is happening with the battery.
i've had my macbook for a little under a year and i think i may have shortened my battery power. i have a tendency to leave my laptop plugged in long past the fully charged time and allow it to run through the battery till it shuts down. i do this when i accidentally fall asleep listening to music or leave for work and forget it's on or plugged in. how hard on the battery or laptop is it to do this repeatedly? when it's fully charged it tells me i have roughly 4 hours of battery power available. is that the right amount? is there anything i should do to protect the battery? the manufacturer warranty will be up in march, should i take it in for a check up while i may have the option of not having to pay for it?
My 2009 MacBook Pro won't at the same socket for long. Charges for a while then I have to move and plug into the socket on the other side of the room. There is still power running through the sockets lamps on etc. and often the charger will show just green.
Then I can reboot work for half an hour until battery is like 50% then it shuts off again... then I can reboot again and work for some more time. I've checked with coconut battery and when the computer stops at 70% I still have like 1700 mAh...I've reset PRAM, power management, etc...
Of course my battery is old, but it should work until 00%... not stop at 70%. Before I spend like 100$ (that is what a macbook pro battery costs here in Mexico) I'm willing to try anything...
I was on a long bus ride and woke up in the morning and noticed everything under my seat was wet including about two inches of one end of my black MacBook. It was in one of those ubiquitous neoprene cases and while not submerged in water it was pretty wet. Oh, and I guess I don't know if it was water or not, but it didn't have an obvious color, smell, etc.
Anyway, I took out the battery and left it out for a little over a day hoping it would dry. When I put it back in and opened it up it seemed everything was working well and I worked on it under battery power for a little while. It suddenly shut off with the battery around 23% (it usually dies at 8%, I don't know why) and when I plugged it in and started up again the battery showed it was charging for about 10 or 20 seconds then said "Not Charging" then I got the little battery with an 'X' in it meaning there is no battery connected.
If I take it out and put it back in again it does the same thing (says it's charging for a moment then ends up with the 'X'). The odd things is that the water was on the non-battery end of the computer, it was on the end with the CD drive, which seems to be working. Okay, right, so is there anything that can be done? Is this battery just a nice, black paperweight? Is there reason to believe that something other than the battery has a problem?
If this battery is toast, where is a good place to buy a new battery? Do official Apple resellers sell them? I'm in Argentina right now and I don't think they have real Apple stores.
My girlfriend's 06 or 07 white macbook is starting to stop charging pretty often. Sometimes toying with the plug or turning it around fixes it, but then it will stop again. She tried it with my roommates plug which seemed to work fine.
I'm not sure if this is SL related, but I get the service battery warning when I click on the battery status. iStat reports it at 62% health. Rev B 1.6 just 6months old. Should I bring it to apple or is it just a bug of SL?
I have just completed rescuing a water damaged MB C2D which was originally a 2.16 and is now a 1.83. Fun project for a cold Sunday afternoon. 5 hrs I have one issue with the MB and that is the charging of the battery. The battery icon sometimes shows 'no battery' or if it shows a battery is recognized, it isn't charging. The LED on the mag-safe charger is always green. The battery is from the water damaged 2.16 and my thinking is that it may have suffered damage from being exposed to water. Original owner left the MB in the backyard and it started to rain!
I calibrated my battery for the first time since Dec. When I plugged it in this morning, it took 3 hours to charge all the way, and now it's stuck on 99% full, 0:00 till completely charged, and I'm getting an error when I click on the battery in the menu bar that says "Service Battery". When I click on the error, it tells me that it may not be functioning properly and to take it to an authorized apple service retailer. Before I waste 2 hours by going to the Apple store and back, has anyone else had this problem, and is there a way to fix it without having it looked at?
recently got hold of a Macbook Pro, Core Duo 2Ghz , all is working fine no issues except the battery does not Charge what so ever ....now it was Supplied with a 60W Power Brick , but i have since found out thats not sufficiant for a Macbook Pro .. but also came Across A Problem in System Profiler ,
Specificly the Part that deals with Power,now the battery charges fine in another Macbook Pro, so i know its not that battery as the person told me ,Here's what it says in AC Charger Information
Connected:Yes ID:0x0000 Wattage (W):0 Revision:0x0000 Family:0x0000 Serial Number:0x00000000 Charging:No
I have a Mac 10.6.8 running Snow Leopard. My battery won't charge: all I get is "Not Charging" in the menu bar battery status; the power adapter doesn't light up either. It's not a problem with the battery—when I put my battery in my friend's MacBook, it worked just fine. His battery, however, wouldn't charge either when it was in my computer. I have tried resetting the SMC several times, following the instructions exactly. I've reset the PRAM, run disk repair, and fixed disk permissions. I don't have the money to take it to a repairman—even if I did, I need my computer every day for work.
I just got my macbook 2.4 a week ago and the battery will now only charge to 99%.
What is the best way to use it to keep the battery in good condition. I am normally near a power source but I read that apple do not advise to use the macbook plugged in so that what I have been doing.
I have the Black Macbook (purchased in 2008) and within the past month, I have been experiencing problems with the battery. I've noticed lately it becoming weak, not being able to last long without being plugged in. However, now when I plug it into the charger, it shows 0%, and if I disconnect the charger, it automatically shuts off. I checked the System Profiler, and the condition of the health shows "Check Battery". What are my next steps from here? I don't want to purchase a new battery, in hopes to get a new Macbook later this summer. Does my Macbook have much life, or should I go ahead and brace myself for a new one?
I just want to say thanks apple for being a piece of **** machine. I have the first macbook 1.83 ghZ 2gb (that I bought from crucial) intel core duo. The problems I have had:-Battery not charging (70? replacement because I had no more warranty)-Burnt and melted charger (also expensive)-And now the problem is unknown all I know it will not start.-Faulty Macbook Air -After the second Macbook Air the charger would not work.I mean you would think that so much money for slow computers would get you reliabilit
